Printing a Row of Stars



    


Here is the answer to the little problem. The parts of the program that don't affect it have been (temporarily) cleared away.




    

        
            

            

            

                
                    
    // collect input data from user
    System.out.print( "How many Stars per Row? " );
    numStars = scan.nextInt() ;


      int star = ;
      
      while ( star <=  )
      {
        System.out.print("*");
        
        
      }

      System.out.println();

                		
            

        
    





Question 21:
Need I ask? Fill in the blanks so that numStars stars are printed.
